Abstract
A method of slow-moving ground target detection and parameter estimation with parallel mode airborne bistatic three-channel synthetic aperture radar (SAR) was presented. According to the characteristic of bistatic SAR, fractional Fourier transform (FrFT) technique was adopt to focus the moving target and improve the signal to clutter ratio, clutter suppression interferometer techniques was adopt then to suppress clutter and estimate the parameters of moving target accurately. From the spatial geometry model and echo signal model of the system, the flying condition of transmitting and receiving plane must satisfy when clutter be eliminate and the method of moving target parameters estimation were derived. Finally, computer simulation results validate its effectiveness.
